The second port insertion tube 64b and the fourth port insertion tube 64d can be arranged at the same height. The first port insertion tube 64a and the third port insertion tube 64c may have a bilaterally symmetrical structure, that is, a structure that is symmetrical with respect to the symmetry reference line L. Similarly, the second port insertion tube 64b and the fourth port insertion tube 64d can also have a symmetrical structure.

In this case, the outer diameter portion 632 is positioned further rearward toward the top in response to the gradually increasing width of the inner diameter portion 631. Therefore, as shown in FIG. 9, the third port insertion tube 64c is closer to the tab 30 than the fourth port insertion tube 64d.

As shown in FIGS. 5 to 7 and 18, a plurality of nozzles 65a, 65b, 65c, and 65d for discharging circulating water into the drum 40 may be provided. Multiple nozzles 65a, 65b, 6
5c and 65d are connected to the first port insertion tube 64a, the second port insertion tube 64b, the third port insertion tube 64c, and the fourth port insertion tube 64d, respectively. Hereinafter, the nozzle communicated with the first port insertion pipe 64a and supplied with circulating water will be referred to as a first nozzle 65a, and the nozzle communicated with the second port insertion pipe 64b and supplied with circulating water will be referred to as a second nozzle. The nozzle 65b communicates with the third port insertion pipe 64c and receives circulating water.
5c, a nozzle communicating with the fourth port insertion pipe 64d and receiving circulating water is called a fourth port insertion pipe 64d.
The nozzle is called 65d.

As described above, the plurality of port insertion tubes 64a, 64b, 64c, 64d each extend horizontally, and correspondingly, the plurality of discharge ports 8484a, 84b, 84c, 84, which will be described later.
d also extend horizontally, so that the supply or guidance of circulating water by each discharge port 84a, 84b, 84c, 84d consists of a horizontal direction.

As described above, the nozzles 65a, 65b, 65c, and 65d can be configured to eject the circulating water supplied in a horizontal direction in a direction forming a predetermined angle with respect to the horizontal.
That is, each of the discharge ports 84a, 84b, 84c, 84d/port insertion tubes 64a, 64b
, 64c, and 64d, the circulating water is supplied in the horizontal direction through the nozzles 65a, 65b,
The direction of discharge by 65c, 65d can be directed upward or downward at a predetermined angle with respect to the horizontal.

FIG. 18 shows an assembly of a gasket and a distribution pipe, and particularly shows the position of the nozzle and the jet width of the nozzle. Referring to FIG. 18, the gasket 60 may include four nozzles 65 as described above. Hereinafter, among the four nozzles 65, the two nozzles 65b and 65d located on the upper side are referred to as upper nozzles 65b and 65d, respectively, and when viewing these from the front again, the one located on the left side is called the first upper nozzle. 65b, and the one located on the right side is called a second upper nozzle 65d.

The upper nozzles 65b and 65d are located above the center O of the gasket 60 and spray circulating water downward. Here, the center O is a predetermined point located on the left-right symmetric reference line L of the gasket 60, and is preferably located at half the height H of the gasket 60, but is not necessarily limited to this. .

When viewed from the front, the first upper nozzle 65b is disposed on the left side of the reference line L and injects circulating water downward onto the right side of the reference line L. When viewed from the front, the second upper nozzle 65b is disposed on the right side of the reference line L and injects circulating water downward onto the left side of the reference line L.

The first upper nozzle 65b and the second upper nozzle 65d can be configured to be symmetrical with respect to the reference line L. Therefore, the first upper nozzle 65b and the second upper nozzle 65d The form of the water stream injected through is also symmetrical with respect to the reference line L.

In addition, the two nozzles located below the upper nozzles 65b and 65d are replaced with the lower nozzle 65a.
, 65c, and when these are viewed from the front again, the one located on the left side is called the first lower nozzle 65a, and the one located on the right side is called the second lower nozzle 65c.

When viewed from the front, the first lower nozzle 65a is disposed on the left side of the reference line L and injects circulating water upward onto the right side of the reference line L.

When viewed from the front, the second lower nozzle 65c is disposed on the right side of the reference line L and injects circulating water upward onto the left side of the reference line L.

The first lower nozzle 65a and the second lower nozzle 65c can be configured to be symmetrical with respect to the reference line L. Therefore, the first lower nozzle 65a and the second lower nozzle 65c The form of the water stream injected through is also symmetrical with respect to the reference line L.

As shown in FIGS. 15 to 17, the nozzle 65a may be formed in the gasket body 63 of the gasket 60, and preferably protrudes from the inner peripheral surface of the outer diameter portion 632. The nozzle 65a may include a nozzle inlet pipe 651 and a nozzle head 652. Specifically, the nozzle inflow pipe 651 has a tubular shape, protrudes from the inner peripheral surface of the outer diameter portion 632, and is connected to the corresponding nozzle head 652.

The nozzle head 652 has a collision surface 652a on which the water discharged from the discharge port 84 collides.
A first side surface 652b (see FIG. 9) and a second side surface 652b are located on both sides of the collision surface 652a.
2c.
A funnel-shaped space is formed by the nozzle inlet pipe 651, and water discharged from the nozzle inlet pipe 651 collides with the collision surface 652a in the space and is then discharged through the nozzle 657.

The first side surface 652b and the second side surface 652c extend from the left side and right side of the collision surface 652a, respectively, and can limit the left and right boundaries of the water flow flowing along the collision surface 652a.

The angle γ between the first side surface 652b and the second side surface 652c is approximately 45 degrees to 55 degrees, and is preferably 50 degrees, but is not necessarily limited to this.

When the spray width of the water stream sprayed through the nozzle 65 is defined as a spray width angle, the spray width angle may be defined by the first side surface 652b and the second side surface 652c.
Specifically, the jet width angle is defined as the angle formed by the first boundary where the collision surface 652a and the first side surface 652b meet, and the second boundary where the collision surface 652a and the second side surface 652c meet. can be done.

As shown in FIG. 17, the injection width angle β1 of the upper nozzles 65b and 65d is different from that of the lower nozzle 6.
It can be smaller than the injection width angle β2 of 5a and 65c. Part of the circulating water supplied to the inflow port 81 is injected through the lower nozzles 65a, 65c while rising along the distribution pipe 801, and the rest is injected through the upper nozzles 65b, 65d. Upper nozzle 65b
, 65d is smaller than the discharge flow rate through the lower nozzles 65a, 65c. Therefore, by making the spray width of the upper nozzles 65b, 65d smaller than the spray width of the lower nozzles 65a, 65c (β1<β2), the discharge water pressure of the upper nozzles 65b, 65d is relatively compensated, and all the nozzles 65a , 65b, 65c, and 65d, water can be discharged with substantially uniform water pressure.

The difference (β2−β1) between the jet width angle β2 of the lower nozzles 65a, 65c and the jet width angle β1 of the upper nozzles 65b, 65d is approximately 4 degrees to 6 degrees, preferably 5 degrees. At this time, β1 is approximately 38 to 42 degrees, preferably 40 degrees, and β2 is approximately 43 to 47 degrees.
degree, preferably 45 degrees.

On the other hand, the injection direction of the upper nozzles 65b, 65d has an upward deviation angle Τ with respect to a line R connecting the center O of the upper nozzles 65b, 65d and the gasket 60 (hereinafter referred to as the "nozzle arrangement line"). It can be done. Here, the injection direction D of the upper nozzles 65b and 65d is
R is defined along a straight line that equally divides the angle formed by the first side surface 652b and the second side surface 652c, and the injection direction DR is directed upward from the nozzle arrangement line R. The upward deviation angle Τ can be between 5 degrees and 9 degrees, preferably 7 degrees.

Depending on various conditions such as the height, position, and jet width angle β1 of the upper nozzles 65b and 65d,
In some cases, water may not be jetted with sufficient water pressure through the upper nozzles 65b, 65d, and the jetted water stream may not be able to travel straight ahead. For this reason, by making the injection direction of the upper nozzles 65b, 65d upward from the nozzle arrangement line R by the upward deviation angle Τ, even when the water pressure of the upper nozzles 65b, 65d is not sufficient, the nozzles The area where the arrangement line R passes can be touched by the water stream, and preferably, as shown in FIG. 17, the upper nozzle 6
The form of the water stream injected through the nozzles 5b and 65d and the form of the water stream injected through the lower nozzles 65a and 65c can be made substantially vertically symmetrical.

On the other hand, when the angle from the lowest point of the gasket 60 to the lower nozzles 65a, 65c is α1, the upper nozzles 65b, 65d are arranged between the position corresponding to the angle α1 and the highest point H of the gasket 60, 180- It can be located above the point corresponding to the angle obtained by equally dividing α1. That is, in FIG. 17, α2 has a larger value than α3. α2-
α3 can be between 18 degrees and 22 degrees, preferably 20 degrees. At this time, α2
can be between 63 degrees and 67 degrees, preferably 65 degrees.

On the other hand, the lower nozzles 65a and 65c are located at approximately 1/3 point (1/3) of the height H of the gasket 60.
3H). In this case, α2 is preferably set in a range where the upper nozzles 65b and 65d are located above 2/3 (2/3H) of the height of the gasket 60, and in this case, α2 is 65 degrees. be able to.

In order to spray the circulating water evenly up and down within the drum 40, the upper nozzles 65b, 65
d and the lower nozzles 65a, 65c are preferably arranged at equal intervals in the height direction, but in this case, because the water jet is weakened by gravity, the water jet jetted from the upper nozzles 65b, 65d is actually There is a problem in that the result is a region lower than what was predicted geometrically. Therefore, when considering the weakening of the water flow due to gravity, the upper nozzles 65b, 6
5d needs to be placed above 2/3H.

Meanwhile, when the pump 901 is activated and circulating water is injected through the lower nozzles 65a and 65c, it is preferable that the water level in the tub 30 does not exceed 1/3H point.

On the other hand, as shown in FIG. 9, when viewed from the front, the injection direction DRa of the lower nozzle 65a is
can form an angle a with respect to the longitudinal direction of the port insertion tube 64a (or the direction in which water flows into the nozzle 65a, that is, the water inflow direction).

Since the nozzle 65a and the nozzle 65c are arranged symmetrically, the nozzle 65c
The angle that the injection direction DRc makes with the port insertion pipe 64c is also a.

When viewed from the front, the injection direction DRb of the upper nozzle 65b can form an angle b with the length direction of the port insertion tube 64b (or the direction in which water flows into the nozzle 65b, ie, the water inlet direction). Here, the angle b can be 133 to 138 degrees. Angle b can be smaller than angle a.

Since the nozzle 65b and the nozzle 65d are arranged symmetrically, the nozzle 65d
The angle that the injection direction DRd makes with the port insertion pipe 64d is also b.

On the other hand, the nozzle inflow pipe 651 extends horizontally and guides water in a horizontal direction. Therefore, the water flow is uniformly advanced without being affected by gravity until it reaches the nozzle head 652, and then is diffused by the collision surface 652a, so that the water flow is uniformly distributed from each nozzle 65a, 65b, 65c, and 65d. Can be sprayed.

If the length direction of the nozzle inlet pipes 651 were not disposed substantially horizontally but were disposed toward the center O of the gasket 60, the water flowing through the nozzle inlet pipes 651 of the upper nozzles 65b and 65d would be subjected to gravity as it flows downward, and would be sprayed into the drum 40 earlier than the lower nozzles 65a and 65c, and the water flowing through the nozzle inlet pipes 651 of the lower nozzles 65a and 65c would be subjected to gravity as it flows upward, and would be sprayed into the drum 40 later than the upper nozzles 65b and 65d, making it difficult to maintain a constant spray pattern of water sprayed into the drum 40 from the multiple nozzles 65a, 65b, 65c, and 65d. However, in this embodiment, the length direction of the nozzle inlet pipes 651 is disposed substantially horizontally, and the water is guided in the horizontal direction, so that the spray pattern of the water sprayed from the multiple nozzles 65a, 65b, 65c, and 65d into the drum 40 is not uniform.
The shape of the water injected into the drum 40 from the nozzles 65b, 65c, and 65d can be kept constant.

Meanwhile, the area of the inlet 651a of the nozzle inflow pipe 651 may be larger than the area of the outlet 651b. The circulating water discharged from the outlet 651b collides with the collision surface 652a of the nozzle head 652, and then is injected into the drum 40 through the injection port 657. The direction of the injection port 657 and the length direction of the nozzle inflow pipe 651 may intersect with each other.

The gasket 60 may include a protrusion 655 protruding from an inner circumferential surface of the gasket body 63. A plurality of protrusions 655 may be formed along the circumferential direction corresponding to the plurality of nozzles 65a, 65b, 65c, and 65d. An injection port 657 of each of the nozzles 65a, 65b, 65c, and 65d may be formed in the corresponding protrusion 655 (see FIG. 9 ).

As shown in FIG. 15, the nozzle inflow pipe 651 can include a flow path reduction portion 651c whose inner diameter becomes gradually narrower in the direction of movement of the water flow. The inner diameter of the flow path reduction portion 651c can gradually become smaller until it reaches the nozzle head 652.

On the other hand, at least a portion of the distribution pipe 801 is connected to the outer peripheral surface of the gasket 60 and the balancer 90.
a, 90b. The distribution pipe 801 can be installed in an existing space (that is, between the outer peripheral surface of the gasket 60 and the balancers 90a, 90b) without the need to secure a separate space for installing the distribution pipe 801.

The pair of upper nozzles 65b and 65d are formed above the inflow port 81, and can be arranged on both sides of the inflow port 81, respectively. A pair of upper nozzles 65b, 65
d is arranged symmetrically with respect to the reference line L passing through the center O (see FIG. 9), and therefore, the injection directions of the respective upper nozzles 65b and 65d are also symmetrical with respect to the reference line L.

The pair of upper nozzles 65a and 65c can be located above the center O or the center C of the drum 40. Each of the upper nozzles 65b and 65d injects circulating water downward, so when looking at the drum 40 from the front, the circulating water passes through the area above the center C of the drum 40 on the inlet side of the drum 40, and The deeper it goes into the interior 40, the more it is injected in a downwardly slanted form.

The pair of lower nozzles 65a, 65c are arranged above the inflow port 81, but below the pair of upper nozzles 65b, 65d. The pair of lower nozzles 65a and 65c are
The lower nozzles 65a and 65c may be arranged on both sides of the inflow port 81, preferably symmetrically with respect to the reference line L, so that the injection directions of the lower nozzles 65a and 65c are symmetrical with respect to the reference line L. be.

The pair of lower nozzles 65b and 65c can be located below the center O or the center of the drum 40. Each of the lower nozzles 65b and 65c injects circulating water upward, so when looking at the drum 40 from the front, the circulating water does not reach the drum 4 on the inlet side of the drum 40.
The deeper the fuel passes through the area below the center C of the drum 40, the more it is injected in an upwardly inclined manner.

Taking the first nozzle 65a as an example with reference to FIG. 17, one end of the nozzle inflow pipe 651 is communicated with the first port insertion pipe 64a, and the other end is opened inside the tab 30. The cross-sectional area of the other end of the nozzle inflow pipe 651 is narrower than that of one end. The nozzle inflow pipe 651 has a hollow 651a formed inside.

The nozzle head 652 interferes with the sprayed circulating water and changes the spraying direction of the circulating water. The nozzle head 652 injects circulating water to the rear inside of the tub 30.

The other end 653 of the nozzle head 652 is spaced apart from the discharge side (other end) of the nozzle inflow pipe 651. The nozzle head 652 is spaced apart from the other end of the nozzle inflow pipe 651 and is disposed to block the nozzle inflow pipe 651. The circulating water collides with the inner surface of the nozzle head 652, and the discharge direction is changed. The other end 653 of the nozzle head 652 is arranged toward the rear of the tab 30.

The circulating water discharged to the nozzle inflow pipe discharge port 651c hits the collision surface 6 of the nozzle head 652.
After colliding with 52a, it is injected into the tub 30 through the injection port 657. Injection port 657
The direction in which the nozzle inflow pipe 651 extends intersects with the direction in which the nozzle inflow pipe 651 extends.

As shown in FIG. 6, the distribution pipe 801 includes an inflow port 81 connected to the circulation pipe 86, a transfer pipe 80 that guides water that has flowed in through the inflow port 81, and a pipe protruding from the transfer pipe 80. A plurality of discharge ports 84a, 84b, 84c, and 84d are provided.

The distribution pipe 801 branches the circulating water discharged from the circulation pipe 86 into a first partial flow FL1.
(see FIG. 13) and a second partial flow FL2 (see FIG. 8). The distribution pipe 801 has at least one discharge port 84b, 84c on a first flow path through which the first partial flow FL1 is guided.

Similarly, at least one discharge port 84d, 72e is formed on the second flow path along which the second partial flow FL2 is guided, and the circulating water is discharged to the corresponding nozzle 65d via the corresponding discharge port 84d, 72e. do. The transfer conduit 80 can include a first conduit section 80a that forms the first flow path, and a second conduit section 80b that forms the second flow path.

One end of the first pipe portion 80a and one end of the second pipe portion 80b are connected to each other, and an inlet port 81 protrudes from the connected portion.
The other end of the second pipeline portion 80a and the other end of the second pipeline portion 80b are separated from each other. That is, the transfer pipeline 80 is generally formed in a “Y” shape, and has a structure in which the circulating water flowing in through one inlet (i.e., inlet port 81) is branched into two flow paths and guided therethrough.

The nozzles 65a, 65b, 65c, and 65d can be divided into upper nozzles 65a, 65d and lower nozzles 65b, 65c depending on their height above the gasket 60. In the embodiment, four nozzles 65a, 65b, 65c, and 65d are provided, including a first lower nozzle 65b, a second lower nozzle 65c, and a lower nozzle 65b, 65c arranged at the lower part of the gasket 60. A first upper nozzle 65a and a second upper nozzle 65d can be provided which are arranged higher.

The discharge ports 84a, 84b, 84c, 84d are connected to the nozzles 65a, 65b, 65c, 6
5d, and each discharge port 84a, 84b, 84c, 84d
supplies circulating water to the corresponding nozzles 65a, 65b, 65c, and 65d.

The discharge ports 84a, 84b, 84c, and 84d are a first upper discharge port 84b that supplies circulating water to the first upper nozzle 65a, and a second upper discharge port that supplies circulating water to the second upper nozzle 65d.
The first lower discharge port 84c supplies circulating water to the first lower nozzle 65b, and the second lower discharge port 84d supplies circulating water to the second lower nozzle 65c. .

The transfer pipe 80 is arranged around the outer circumference of the gasket 60 and is connected to the pump 901 via the circulation pipe 86. Each discharge port 84a, 84b, 84c, 84d is
It protrudes inward from the transfer pipe 80 along the radial direction, is inserted into the gasket 60, and supplies circulating water to the corresponding nozzles 65a, 65b, 65c, and 65d.

The distribution pipe 801 has an inflow port 8 that protrudes from the transfer pipe 80 and is connected to the circulation pipe 86.
1 can be provided. The inflow port 81 may protrude outward from the transfer conduit 80 in a radial direction.

FIG. 11 is a front view of the distribution pipe. As shown in FIG. 11, the first conduit section 80a can include a first section 851 to a fourth section 854. The second conduit section 80b is
The configuration is symmetrical to the first conduit section 80a, and the configuration is substantially the same as that of the second conduit section 80a.
b. Therefore, the explanation regarding the first conduit section 80a can also be applied to the second conduit section 80b.

A first section 851 extends from the inlet port 81 . The first section 851 is an arc-shaped (or arc-shaped) section that extends with a predetermined curvature. In an embodiment, the first section 8
51 is a curved shape having a substantially constant curvature, but the shape is not limited to this, and depending on the embodiment, it may be a shape in which two or more curved lines having mutually different curvatures are connected.

The second section 852 may be continuous from the first section 851 and may extend outward from the first section 851 . In other words, the second section 852 is the first section 85
This corresponds to a portion that extends by a distance L2 after being bent outward (that is, in a direction away from the center O) at the upper end of 1. The length L2 of the second section 852 can be shorter than the length L1 of the first section 851.

The third section 853 is a portion that is bent inward from the second section 852 (that is, in a direction closer to the center O) and then further extends by a distance L3. The third section 853 can extend substantially vertically upward from the second section 852. Lower discharge port 84
a is formed in the third section 853 and can extend in a horizontal direction (or in a direction perpendicular to the second section 852).

In the third section 853, the first flat surface 8 from which the lower discharge port 84a is projected
60a can be formed flat. First flat surface 860a can extend vertically. At least a portion of the first flat surface 860a may be brought into contact with the outer peripheral surface of the gasket body 63. Furthermore, the end of the port insertion tube 64a can be brought into close contact with the first flat surface 860a.

The fourth section 854 is bent inward from the third section 853 (that is, in the direction closer to the center O), and then further extended by a distance L4 to reach the end of the first conduit section 80a. up to. The upper discharge port 84b can be formed in the fourth section 854, and is preferably formed at the end of the fourth section 854, as in the embodiment. The fourth section 854 may have a curved shape with a predetermined curvature, and may extend in a direction intersecting the length direction of the upper discharge port 84b.

At the end of the first conduit portion 80a (or the end of the fourth section 854), the second flat surface 860b from which the upper discharge port 84b is projected may be formed flat. The second flat surface 860b can extend vertically. In this case, surface 860a
and the second flat surface 860b are parallel to each other. At least a portion of the second flat surface 860b may be in close contact with an end of the port insertion tube 64b.

On the other hand, since the fourth section 854 is bent inward from the third section 853, when viewed from the front, the second flat surface 860b on which the upper discharge port 84b is formed.
is located closer to the symmetry reference line L than the second flat surface 860a where the lower discharge port 84a is formed. Furthermore, the second flat surface 860b is desirably closer to the outer peripheral surface of the gasket body 63 than the first flat surface 860a.

On the other hand, 860c, which is not illustrated in FIG. 11, is a flat surface from which the lower discharge port 84c is projected, and 860d is a flat surface from which the upper discharge port 84d is projected.

Further, when viewed from the front, the terminal end of the upper discharge port 84b is the lower discharge port 84a.
It is located at a point further closer to the symmetry reference line L by a distance S than the terminal end of the line.

As shown in FIGS. 11 and 12, the first pipeline portion 80a may have a lower port connection portion 858 formed at a portion connected to the lower discharge port 84a, and an upper port connection portion 857 formed at a portion connected to the upper discharge port 84b.

Similarly, the second conduit portion 80b may have a lower port connecting portion 868 formed in a portion connected to the lower discharge port 84c, and an upper port connecting portion 867 formed in a portion connected to the upper discharge port 84d. .

As shown in FIG. 12, each of the port connection parts 857, 858, 867, and 868 may have a shape that bulges forward compared to the peripheral part when viewed from the side. The width P of each port connection portion 857, 858, 867, and 868 may be greater than the width W of the peripheral portion. In other words, the conduit sections 80a and 80b extend from the inflow port 81 to a certain width W, and after bulging and projecting forward from the port connection sections 858 and 868, the width becomes narrow again to W, and the width becomes narrower to the port connection section 857. , 878. On the other hand, port connection parts 857, 858, 8
The width P of 67, 868 can be larger than the diameter t of the discharge port 84a.

On the other hand, as shown in FIG. 15, each discharge port 84a, 84b, 84c, 84d
A ring-shaped press-fit protrusion 869 extending in the circumferential direction may be formed on the outer peripheral surface of. Press-fit protrusion 8

4b, 84c, 84d into the port insertion tubes 64a, 64b, 64c, 64d,
Since the press-fit protrusions 869 press against the inner peripheral surfaces of the port insertion tubes 64a, 64b, 64c, and 64d, the bonding force is increased.

The discharge ports 84a, 84b, 84c, and 84d are connected to the port insertion tubes 64a, 64b, and 64c.
, 64d is defined as a first direction, the press-fit protrusion 869 may have a vertical surface and an inclined surface that is gradually lower in height from the vertical surface toward the first direction.
When the distribution pipe 801 is inserted into the port insertion pipes 64a, 64b, 64c, 64d, the inclined surface makes it easy to press-fit the distribution pipes 801, and after the press-fit is completed, the vertical surface prevents the discharge ports 84a, 84b, 84c, 84d from easily slipping out of the port insertion pipes 64a, 64b, 64c, 64d. Since the distribution pipe 801 can be connected to the gasket 60 without using a fastening member (e.g., a clamp), no work time is required to fasten the fastening member.

On the other hand, when inserted into the port insertion tubes 64a, 64b, 64c, 64d, the ends of the discharge ports 84a, 84b, 84c, 84d can reach the nozzle inflow tube 651,
At this time, the inner peripheral surfaces of the discharge ports 84a, 84b, 84c, and 84d and the inner peripheral surface of the nozzle inflow pipe 651 form a substantially continuous surface, thereby reducing the resistance of the circulating water. The nozzle inflow pipe 651 has a tubular shape, protrudes from the inner peripheral surface of the outer diameter portion 632, and is connected to the corresponding nozzle head 652.

12a and a second circulation port 912b.

The water flow formed while the impeller 915 is rotated by the pump motor 92 is simultaneously discharged through the first circulation port 912a and the second circulation port 912b; The water discharged through the second circulation port 912b is supplied to the first distribution pipe 802 through a first circulation pipe (not shown), and the water discharged through the second circulation port 912b is supplied to the first distribution pipe 802 through a first circulation pipe (not shown).
It is supplied to the second distribution pipe 803 via a circulation pipe (not shown).

FIG. 23 is an enlarged view of a structure in which a press-fit protrusion is formed in a discharge port in a distribution pipe according to an embodiment of the present invention. FIG. 24 is a partial view showing a discharge port in a distribution pipe according to still another embodiment of the present invention. FIG. 25 is a sectional view showing a state in which the discharge port of the distribution pipe shown in FIG. 24 is inserted into the port insertion pipe. FIG. 26 is an enlarged view of part A in FIG. 25.

23 to 25, the press-fit protrusion 86 formed on the upper discharge port 84b will be described below.
9 and the terminal projection 842, it being understood that these projections 869, 842 may also be applied to the other discharge ports previously described with reference to FIGS.

As shown in FIGS. 23 to 25, the press-fit protrusion 869 can be formed on the outer peripheral surface of the discharge port 84b. A terminal protrusion 842 may be formed at the terminal end of the discharge port 84b.

According to an embodiment, the discharge port 84b may be formed with only a press-fit protrusion 869 as shown in FIG. 23, or may be formed with both a press-fit protrusion 869 and a terminal protrusion 842 as shown in FIG.

The nozzle 65b may have a gradually decreasing diameter from the inlet portion 661 to the outlet portion 662. As the discharge port 84b is pressed into the nozzle 65b toward the outlet portion 662, the smaller diameter outlet portion 662 presses the end portion of the discharge port 84b more firmly, thereby decreasing the diameter of the discharge port 84b.
and nozzle 65b.

The outlet portion 662 includes an annular stepped portion 662a toward the inside of the drum 40. The terminal protrusion 842 is formed at the terminal end of the discharge port 84b, and is engaged with the stepped portion 662a when the discharge port 84b is press-fitted into the nozzle 65b.

The terminal protrusion 842 is formed in a ring shape so as to protrude along the terminal end of the discharge port 64b, and a predetermined inclined surface 842a is formed in the direction of pressing the discharge port 64b, and a vertical surface 842b is formed in the opposite direction to pressing the discharge port 84b, and the vertical surface 842b and the step portion 662a abut and simultaneously engage with each other.

Since the inclined surface 842a is formed in the press-fitting direction of the discharge port 84b, the end protrusion 842 can be moved gently until it is stopped by the stepped portion 662a. In addition, the vertical surface 842b
Since the vertical surface 842b and the stepped portion 662a are in surface contact with each other, the adhesion between the vertical surface 842b and the stepped portion 662a is improved, and the discharge port 84b is not easily removed even if a force is applied to the discharge port 84b in the opposite direction to the press-fitting direction.

On the other hand, the stepped portion 662a is formed in the opposite direction to the direction of the force that the discharge port 84a receives due to the supply of circulating water into the drum 40, and prevents the discharge port 84a from coming off and connects the discharge port 84b to the gasket 60. Fix it.

In conclusion, at the inlet part 661, the movement of the discharge port 84a is restricted by the press-fit protrusion 869, and at the outlet part 662, it is also fixed by the engagement between the terminal protrusion 842 and the stepped part 662a, so that the circulating water Even if water pressure, vibration, and various other external forces are applied during the circulation process,
Distribution pipes 801, 802, 803 are not easily removed from gasket 60.

On the other hand, all the contents regarding the press-fitting protrusion 689, the terminal protrusion 842, and the connection relationship between the protrusions and the like described above are applicable to this embodiment and other embodiments.

As shown in FIG. 11, the outer diameter of the first discharge port 84a is referred to as t1, and the inner diameter is referred to as D1.
The inner cross-sectional area is called DA1. The outer diameter of the second discharge port 84b is referred to as t2, the inner diameter is referred to as D2, and the inner cross-sectional area (or flow path cross-sectional area) is referred to as DA2. The inner diameter (or flow path cross-sectional area) of the inflow port 81 is referred to as D3, and the inner cross-sectional area is referred to as DA3.

Washing water flowing in through the inflow port 81 flows through the first pipe section 80a and the second pipe section 80.
b and then guided upward. The washing water guided upward along the first pipe section 80a is sequentially discharged through the first discharge port 84a and the second discharge port 84b, and similarly flows into the second pipe section 80b. The washing water guided upward is sequentially discharged through the third discharge port 84c and the fourth discharge port 84d.

As the water flows upward along the pipes 80a and 80b, the water pressure gradually decreases. Specifically, as shown in FIG. 12, the water pressure PA (the water pressure at the point indicated by A in FIG. 11) is the largest at the inlet port 81, and the water pressure PB (the water pressure at the point indicated by A in FIG. 11) is the largest at the first and third outlet ports 84a and 84c.
The water pressure at the point indicated by B is next, and the second and fourth discharge ports 84b, 84d
The water pressure PC at the point indicated by C in FIG. 11 is the smallest. (PA>PB>P
C)

As mentioned above, the discharge ports 84a and 84c located on the lower side (hereinafter referred to as lower discharge ports) and the discharge ports 84b and 84d located on the upper side (hereinafter referred to as upper discharge ports).
Since a water pressure difference occurs between the upper and lower discharge ports 84b and 84d, if the inner diameters are the same, the discharge flow rate of the upper discharge ports 84b and 84d must be smaller than that of the lower discharge ports 84a and 84c.

In order to correct such a difference in the discharge flow rate between the upper/lower discharge ports 84a, 84b, 84c, and 84d, in this embodiment, the flow passage cross-sectional area DA2 of the upper discharge ports 84b, 84d is The flow path cross-sectional area DA1 of the discharge ports 84a and 84c was made larger than that of the discharge ports 84a and 84c. Preferably, PB*DA1=PC*DA2. Moreover, desirably, DA1>DA2
>DA3.

On the other hand, the distribution pipe 80 is arranged between the outer peripheral surface of the gasket body 63 and the balancer 90. More specifically, as shown in FIG. 10, at least a portion of the distribution pipe 80 can be disposed in a recessed portion 67 formed in the outer peripheral surface of the gasket body 63. First pipe section 8
The recessed portion 67 corresponds to the gasket body 6 and the second conduit portion 80b, respectively.
3, respectively. (See 67(1) in FIG. 5 and 67(2) in FIG. 7.
)

One end of the circulation pipe 86 is connected to an inlet port 81 protruding from the bottom of the distribution pipe 80.
The other end is connected to the discharge port 84 of the pump 901. When the pump is provided at a position facing the inlet port 81 of the discharge port in a straight line, the circulation pipe 86 may be a straight pipe. However, in other cases, the circulation pipe 86 may be formed by bending.

The circulation pipe 86 may be made of a material that is flexible but maintains its shape, and in an embodiment of the present invention, is made of EPDM (ethylene propylene diene monomer).
merrubber).

The recessed portion 67 is formed on the outer peripheral surface 61 of the gasket body 63, and is formed on the outer circumferential surface 61 of the gasket body 63, and is
At least a portion of 0b may be anchored within the recess 67. The recessed portion 67 may be formed by recessing a portion of the outer peripheral surface 61 of the gasket body 63 inward. Specifically, a partially raised portion may be formed on the outer peripheral surface 61 of the gasket body 63, and a depressed portion 67 may be formed in the raised portion.

During the rotation of the drum 40, the tabs 30 will vibrate, and the vibrations of the tabs 30 can cause the flexible gasket 60 to fold or expand, thereby also vibrating.

The casing 10 and the tab 30 can be regarded as rigid bodies, so that deformation of the portion where the gasket 60 is connected to the casing 10 and the tab 30 is negligible. Therefore, by forming the recess 67 at a position closer to the tab connection portion 62 than to the casing connection portion 61 (see FIG. 10), excessive deformation of the recess 67 can be prevented, and the transfer pipe 80 can be stably fixed to the recess 67. In this respect, the recess 67 is formed on the outer diameter portion 6
It is preferable that the nozzle is formed at 32.

The recess 67 can extend circumferentially from around the gasket body 63. The depressed portion 67 can include a bottom surface 63a that forms the bottom of the groove, and a side surface 63b that extends radially outward from the bottom surface 63a and forms the side surface of the groove. The recessed portion 67 may have an open rear surface facing the tab 30, and a front surface facing the front panel 11 defined by the side surface 63b.

The cross section of the transfer pipes 80a and 80b may have an outer shape in which the height defined in the radial direction is shorter than the width defined in the length direction of the gasket 60 (or the front-rear direction of the washing machine). That is, in the cross section of the transfer pipes 80a and 80b, the width corresponding to the bottom surface 63a of the recessed part 67 may be longer than the height corresponding to the side surface 63b of the recessed part. For example, the transfer pipe 80
The cross sections of a and 80b can be approximately rectangular, and in this case, the long side of the rectangle has the above-mentioned width, and the short side has the above-mentioned height.

In the outer shape of the transfer pipe 80, the height corresponds to the distance between the gasket 60 and the balancer 60, so as described above, the outer shape where the height is shorter than the width corresponds to the distance between the gasket 60 and the balancer 90. This has the advantage that the transfer line 80 can be easily provided within a narrow space.

In order to allow the transfer conduits 80a and 80b to be located within the recess 67, the width of the bottom surface 63a of the recess may be equal to or larger than the width of the transfer conduit 80.

The recess 67 is formed in a substantially U-shape similar to the transfer pipeline 80, and both upper ends of the U-shape are connected to both upper ends of the transfer pipeline 80 (i.e., the upper end of the first pipeline portion 80a and the upper end of the second pipeline portion 80b).
In other words, although the recesses 67 extend in both directions along the circumferential direction at the bottom side of the gasket 60, one of the recesses 67 may extend higher than the upper end of the first pipe line portion 80a and the other may extend higher than the upper end of the second pipe line portion 80b.

Alternatively, the recesses 67 may be formed on both the left and right sides of the reference line L. In this case,
The recesses 67 on both sides are separated from each other. At least a portion of the first transfer pipe 80 is fixed in the recess formed on the left side, and at least a portion of the second transfer pipe 8 is fixed in the recess formed on the right side.
At least a portion of the zero can be fixed.

Preferably, a horizontal line passing through the center O of the gasket 60 is aligned with the gasket 60 as described above.
It passes through depressions 67 formed on both sides. The casing 10 has a rectangular parallelepiped shape that is longer in the vertical direction than in the horizontal direction, and in this case, the distance between the tab 30 and the casing 10 is narrower on the left and right sides of the tab 30 than on the upper and lower sides. Therefore, casing 1
By locating the recessed part in the part where the horizontal line passes through which is the narrowest interval between the first and second conduit parts 80(a) and 800(b) and the side surface of the casing 10, can be spaced apart.

FIGS. 21 and 22 are partial views showing a state in which a distribution pipe is provided on a gasket,
In particular, it is a diagram showing a residual water discharge port and a residual water recovery port formed in the gasket.

As shown in FIGS. 21 and 22, the gasket 60 is formed with a residual water outlet 69h for discharging water remaining on the inner peripheral surface of the gasket body 63 (hereinafter also referred to as "residual water"). obtain.

The residual water discharge port 69h may be connected to the outside of the washing machine or to the pump 901 through a predetermined pipe. In the latter case, the residual water discharge port 69h may be discharged through the drain pipe 74 when the second impeller is rotated.

However, this is not limited to the above, and the residual water discharge outlet 69h can also be connected to the tub 30 to collect the residual water in the tub 30, as will be described in more detail below.

A residual water recovery port 39h may be formed in the tab 30. The remaining water recovery port 39h may be formed on the front surface 31 of the tub 30. A residual water recovery pipe 100 may be provided that communicates the residual water recovery port 39h and the residual water discharge port 69h.

The residual water recovery port 39h is located below the residual water discharge port 69h, so that the residual water accumulated on the inner peripheral surface of the gasket body 63 is removed via the residual water discharge port 69h and the residual water recovery pipe 100. The water can be naturally drained to the water recovery port 39h.

A residual water discharge port 69 that communicates with the residual water discharge port 69h may be projected downward from the outer circumferential surface 61 of the gasket body 63. A residual water recovery port 39 that communicates with the residual water recovery port 39h may be projected forward from the front surface 31 of the tab 30.

The residual water discharge port 69 may be connected to the upper end of the residual water recovery pipe 100, and the residual water recovery port 39 may be connected to the lower end of the residual water recovery pipe 100. Specifically, both ends of the residual water recovery pipe 100 may be inserted into the residual water discharge port 69 and the residual water recovery port 39, respectively. In this case, the residual water recovery pipe 100 and the residual water recovery pipe 100 can be fixed by tightening both ends of the residual water recovery pipe 100, which overlap with the residual water discharge port 69 and the residual water recovery port 39, using clamps.

The inflow port 81 of the distribution pipe 801 is located on one side of the residual water discharge port 69. When viewed from the front, the inflow port 81 and the residual water discharge port 69 are arranged in areas that do not overlap with each other, so that when the residual water recovery pipe 100 is provided, it can be prevented from interfering with the inflow port 81.

On the other hand, the residual water discharge port 69 is connected to the lower end of the first balancer 90a and the second balancer 90b.
can be placed between the bottom edge of the The inflow port 81 is connected to the residual water discharge port 69 and the first
balancer 90a, or between the residual water discharge port 69 and the second balancer 90b.

The residual water discharge port 69 is connected to the plurality of discharge ports 84 in order to smoothly discharge circulating water injected from the discharge port 84 or the nozzle 66 when it accumulates on the inner peripheral surface of the gasket.
a, 84b, 84c, and 84d, the discharge port 84a, 84c located at the lowest position and/or the nozzle 65a, 65c located at the lowest position can be disposed at a lower side.

When the gasket 60 is viewed from the front, the lower center portion that meets the reference line L may be the lowest point of the gasket 60. A residual water discharge port 69 may be formed at the lower central portion.

The distribution pipe 80 is arranged on the outer peripheral surface 61 of the gasket body 63 so as to be close to the tab 30, and the residual water discharge port 69 is connected to the transfer pipes 80a, 80b to avoid interference with the distribution pipe 80.
It can be placed further forward.

The remaining water recovery port 39h or the remaining water recovery port 39 may be formed below the transfer pipes 80a and 80b. The residual water recovery pipe 100 is arranged in front of the circulating water supply pipe 80,
The residual water discharge port 69 and the residual water recovery port 39 can be connected.

On the other hand, when the residual water discharge port 69 is formed at the center of the lower side of the gasket body 63 and the residual water recovery port 39h is also arranged vertically below the residual water discharge port 69, the residual water recovery pipe 100 is , and in this case, the inflow port 81 is arranged along a vertical line.
In order to avoid interference with the residual water recovery pipe 100, it must be spaced a predetermined distance away from the residual water discharge port 69 (for example, on the right side).

The farther the inflow port 81 is from the center, the more difficult it may be to distribute the flow evenly to both the first conduit section 80a and the second conduit section 80b. When considering this point, the inflow port 81 is made as narrow as possible by arranging the residual water recovery port 39 on one side (for example, the left side) of the residual water discharge port 69 instead of lining it up on a vertical line passing through the center. It can be placed close to the vertical line.

Meanwhile, the residual water discharge port 69 may be formed in the gasket body 63. The residual water discharge port 69 may protrude from the lower region on the outer peripheral surface of the gasket body 63 . The remaining water discharge port 69 desirably protrudes from the outer diameter portion 632, but is not limited thereto, and may also protrude from the inner diameter portion 631.

Although the embodiments of the present invention have been described above with reference to the attached drawings, the present invention is not limited to the above embodiments, and can be manufactured in various forms different from each other. Those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical spirit or essential features. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
